  Set multiple value's on multiple times without keyframes

  Posted by Yvonne Van de kop on February 23, 2022 at 8:56 am

  Hi there,

  Sometimes I need to make animations without using keyframes and it always works fine with the linear expression if I need only 2 value’s at 2 times. Hope that makes sense…

  
  

  In this case it’s specifically about Time Remap. The idea is really simple but I just can’t get it right. The result must be like this:

  At frame 0 > Time Remap at 0

  Second frame controlled by slider > Time Remap at 181

  At frame 250 > Time Remap at 200

  The first value and the last value I can set with keyframes but I’ve no idea how to add the middle value at a time controlled by a slider.

  Anyone?

  Hey Yvonne, its as simple as making if/else statement in timeremap.

  Pseudo code as follows:

  if (frame > 0) {
  //do your interpolation
  } else if (frame > 250) {
  //do your interpolation
  } else {
  //set default values when condition is not met or is in between, if needed
  }

  Solved it like this now. Don’t know why I didn’t think about the if/else statement haha

  var Dur = comp("00 MASTER CONTROL").layer("MASTER CONTROL").effect("Duration endpage")("Slider");
  var AS = framesToTime(0);
  var AE = framesToTime(181);
  var AC = framesToTime(200);
  var OP1 = linear(time, 0, Dur, AS, AE);
  var OP2 = linear(time, Dur, 10, AE, AC);
  
  if (time < Dur) {
  OP1
  } else {
  OP2
  }
